Generally, the standard tire pressure range set by the original manufacturer for cars is between 2.2 bar and 2.8 bar, with the maximum tire pressure reaching 3.5-4.2 bar, while the actual maximum pressure it can withstand is even higher. The maximum pressure a tire can bear is printed on the side of the tire, usually labeled as "max-press," followed by the number indicating the tire's calibrated maximum pressure. Related information is as follows: Hazards of overinflated tires: Tire friction and adhesion will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort; it accelerates localized wear on the central tread pattern, shortening tire lifespan; vehicle vibration increases, indirectly affecting the lifespan of other components; it causes excessive stretching deformation of tire cords, reducing tire elasticity and increasing the load on the car during driving; it also decreases puncture resistance. Hazards of underinflated tires: Friction coefficient with the road surface increases, leading to higher fuel consumption; it makes the steering wheel heavy and prone to deviation, creating unsafe driving conditions; it increases movement in various parts of the tire, causing abnormal heating due to excessive rolling; it reduces the functionality of cords and rubber, leading to delamination or cord breakage, and excessive friction between the tire and rim, causing damage to the bead area and abnormal wear.
